GF1003M

Speakers Overview

The GF1003M is an electromagnetic speaker manufactured by Same Sky, designed for frame mounting applications. It features a round shape with a ferrite magnet and a polyethylene terephthalate (PET) cone. The unit operates at an impedance of 8 Ohms and has a power rating of 3 W. Key acoustic parameters include a sound pressure level of 93 dBA and a frequency response centered around 250 Hz. Physical dimensions are approximately 93.5 mm in diameter, with overall length and width of 102.4 mm and a depth of 36.2 mm. It utilizes solder eyelets for termination and functions within a temperature range of -25 C to +60 C.

Speakers Feature Summary

• Utilizes a ferrite magnet structure paired with a PET cone for durable audio reproduction.
• Designed for direct frame mounting to facilitate integration into various enclosures.
• Features solder eyelet termination for straightforward electrical connection.

Speakers Applications

• General purpose audio output devices
• Industrial control panel indicators
• Appliance status signaling

Speakers Procurement Notes

Verify the specific manufacturing date code against current RoHS compliance requirements before finalizing procurement. Confirm that the operating environment remains within the specified -25 C to +60 C thermal limits to ensure long-term reliability. Ensure mechanical mounting holes align with the 102.4 mm x 102.4 mm frame dimensions. Validate that the 8 Ohm impedance matches the driving circuit specifications to prevent damage or inefficient power transfer.

Speakers Selection Notes

Select this component when a robust, high-output speaker is required for frame-mounted installations. The 3 W power handling and 93 dBA sensitivity make it suitable for environments requiring clear audible signals. Consider the physical depth of 36.2 mm during enclosure design to ensure adequate clearance. The use of standard solder eyelets simplifies wiring compared to surface-mount alternatives.

Speakers Part Context

This speaker belongs to the broader category of electromagnetic audio transducers produced by Same Sky. It represents a standard solution for applications needing reliable sound generation without complex electronic drivers. The design prioritizes mechanical stability and acoustic efficiency over miniaturization, distinguishing it from smaller micro-speaker variants found in portable electronics.
